Job Description for Cloud Architect (Azure, AWS & Oracle OCI) Multi-Cloud Architecture • Security & Governance • Enterprise-Scale Delivery Position Summary The Cloud Architect is responsible for designing, governing, and evolving SDD’s multi-cloud architecture across Microsoft Azure, Amazon Web Services (AWS), and Oracle Cloud Infrastructure (OCI). The role ensures cloud platforms are secure, scalable, cost-efficient, resilient, and compliant with government and enterprise standards while supporting diverse workloads such as Iaa S, Paa S, container platforms, databases, DR, and digital services. This is a highly technical role requiring strong hands-on experience, deep architectural thinking, and the ability to guide engineering teams and senior stakeholders through complex cloud decisions.
Core Responsibilities1. Multi-Cloud Architecture & Strategy Design and maintain reference architectures for:Azure, AWS, and Oracle OCIHybrid and multi-cloud connectivity Sovereign cloud and data residency models Define cloud adoption patterns for:Iaa S & Paa S workloads Container platforms (AKS, EKS, OKE) Database services (Azure SQL, RDS, Autonomous DB, Exadata) DR and business continuity Ensure consistency and interoperability across cloud providers.
2. Cloud Landing Zones & Foundations Architect and govern cloud Landing Zones for:Identity & access management Network segmentation Security baselines Logging and monitoring Cost management & tagging Implement enterprise standards for:Account/subscription structures Network hubs & spokes Shared services Multi-tenant isolation
3. Networking & Connectivity Design secure connectivity:Site-to-site VPNClient VPNExpress Route / Direct Connect / Fast Connect Inter-cloud connectivity Define cloud network architectures:VPC/VNet design Subnetting and routing Load balancing DNS and traffic management
4. Security Architecture & Governance Define and enforce cloud security architecture:IAM, RBAC, least privilege Encryption at rest and in transit Key management (KMS, HSM) Secure network segmentation Zero Trust principles Ensure compliance with:Government security regulations ISO 27001 / NISTCloud Security Alliance (CSA) guidance Collaborate with security teams on threat models and controls.
5. Platform, Paa S & Container Architecture Architect cloud-native platforms including:AKS, EKS, OKEServerless (Azure Functions, Lambda) API gateways and integration services Define standards for:CI/CD integration Dev Sec Ops pipelines Observability and monitoring Support application modernization and cloud-native adoption.6. Resilience, DR & Availability Design HA/DR architectures:Multi-AZ / multi-region Backup & replication strategies Cross-cloud DR scenarios Define RTO/RPO targets and validate DR designs through testing.7. Cost Optimization & Fin Ops Alignment Work closely with Fin Ops teams to:Define cost-efficient architectures Optimize resource sizing Implement tagging and chargeback models Evaluate reserved instances and savings plans Ensure architectural decisions consider long-term cost impact.8. Technical Leadership & Governance Review and approve cloud designs and build documents. Guide engineering teams and vendors during implementation. Act as escalation point for complex technical challenges. Maintain architectural standards, patterns, and documentation.9. Documentation & Stakeholder Engagement Produce high-quality documentation:Reference architectures Solution designs Standards and guidelines Decision records Present technical designs and trade-offs to senior management and governance boards.
Required Experience10–15 years of IT experience, with 7+ years in cloud architecture roles. Strong hands-on experience across:Azure (core requirement) AWS (core requirement) Oracle OCI (core requirement) Proven experience designing and operating enterprise-scale, multi-cloud environments. Experience in government, regulated, or large enterprise environments is highly preferred.
Skills & Competencies Technical Skills Deep expertise in:Azure (Networking, Identity, Paa S, Security, DR) AWS (VPC, IAM, EC2, RDS, EKS, Security) OCI (VCN, IAM, Autonomous DB, Exadata, Fast Connect) Strong understanding of:Cloud networking & security Hybrid connectivity Containers and orchestration Cloud-native design patterns Soft Skills Strong analytical and problem-solving skills. Ability to explain complex technical concepts clearly. Strong documentation and presentation skills. Leadership mindset with collaborative approach.
